Claims. (Cl. 222-542) ing of thecharacter stated wherein provision is made for avoiding presentation of raw metal edges interiorly of the container structure.

Another objectl of the invention isy to-provide a spout mounting of the character stated wherein the spout registering opening isturned in a manner for reinforcing the opening andv imparting rigidity to the annular seat.

ln its more detailed nature the invention seeks to provide a spout mounting of the character stated wherein the spout-comprises a tubular externally threaded plastic body t havingian outwardly extending slightly downwardly dished peripheral flange, and wherein a wall of the container is equipped with an opening with which the spout opening registersfand an annular seat opposed by the spout flange andi defined' by an upstanding wall portion formed by an annular fold? in said container wall including a portion bent inwardly and downwardly over the spout llange to secure the same on the seat, there being included a sealing material on the annular seat and into which the peripheral edge portion of the spout flange is caused to securely bite by the overhanging container wall fold.

Another object of the invention is to provide a spout mounting of the character stated wherein the annular seat includes an upwardly turned edge defining the spout registering opening and which is` received or embedded and shielded from view and contact in an annular clearance in the bottom face of the spout.

Another object of the invention is to provide a spout mounting of the character stated wherein the spout registering opening defining edge is turned in the form of a reinforcing hem.

A further object of the invention is to provide a spout mounting of thecharacter stated wherein the spout registering opening defining edge is turned in the form of a downwardly and outwardly directed curl.

A still further object of the invention is to provide a spoutmounting of the character stated wherein the spout includes a depending cylindrical extension snugly received in. thereinforced spout registering opening,

With the above and other objects in View that will hereinafter appear, the nature of the invention will be more fully understood by following the detailed description, theappended claims and the severaly views illustrated in the accompanying drawings.

In thedrawings:

Figure l isa fragmentary vertical cross sectional view illustrating one.. form of spout mounting, parts being broken away and in section.

Figure 2 is an enlarged fragmentary sectional view illustratingthe mounting of Figure l.

. Figulre 3 is. a view similar to Figure 2 illustrating a modiliedl form of mountingwherein the spout registering opening is reinforced by an outwardly or upwardly turned hem.

Figure 4 is a View similar to Figure 2 illustrating another modified form of mounting wherein the. spout` registering opening is reinforced by an inwardly or downwardly turned hem, the spout also including a cylindrical extension snugly fitting within the opening.

Figure 5 is a view similar toFigure 4 illustrating still another modified form of mounting wherein the spout registering opening is reinforced by a downwardly and outwardly directed curl.

ln the form of the invention shown in Figures l and 2 the novel spout mounting is illustrated as incorporated in a container top or breast 5 which issecured by a'co'nventional double seam 6 to a container body 7i The spout or nozzle generally designated 8`is in the'form of a tubular body 9 which is externally threaded at 10 and preferably formed of polyethylene, a resilient deformable plastic, although it is to be understood that the same'may be formed of other plastics, including those which harden upon curing. The tubular body 9 includes an outwardly projecting ange 11 at its lower end extremity, and this flange is slightly dished downwardly to providel av peripheral dip at 12`. The breast or top 5 has an annular horizontal seat 13 within the center of which a spout registering opening 14 is provided. In this instance the opening is defined and reinforced by an upturned edge 15, It will be apparent by reference to Figure 2 that the reinforcing edge is turned upwardly at anl angle of The seat-13 is defined outwardly by an upstanding wall in the form of an annular fold 16 including a portion 17 bent inwardly and downwardly over the spout liange 11. A sealing compound 18 is provided on the seat beneath the f flange 11, and the overbending of the fold at 17 serves nozzle or spout is employed, bites into the nozzle at 19 and is shielded from view and Contact in the manner clearly illustrated in Figures 1 and 2. In this manner presentation of raw metal edges internally of the containery is avoided.

In Figure 3 a slightly modified form of mounting is illustrated. This mounting is the same as the previously described mounting except for the factv that there is no embedding of the spout registering opening reinforcing edge into the base of the spout or nozzle. In this modilied mounting the reinforcing of the opening defining edge is by au outwardly or upwardly directed hem 2`0.

ln Figure 4 of the drawing another slight modification of the mounting is illustrated whereinthe reinforcing of the spout registering opening ldefining edge is by a downwardly or inwardly directed hem 21, and in this mounting the spout or nozzle also is shown as including a cylindrical extension 22 which depends from the spout through the top or breast opening and snugly fits within the hem 21.

Another slightly modified mounting is illustrated in Figure 5. In this form of the invention the reinforce'- ment of the nozzle or spout registering opening is by wayof forming a downwardly and outwardly directed curl 23 in the opening delining edge. The spout or nozzle may also be provided with a cylindrical extension 24 depending within and snugly fitting the curl in the manner illustrated.`

[t is to be understood that in each ofthe previously seat defining fold 16 is in opstanding condition. After this-preliminary application the fold is bent over at 17 as previously described to secure the spout in place and firmly press the peripheral flange dip into the underlying sealving compound. This attachment serves to firmly press the angle turned edge into the deformable base of the spout if polyethyleneor a comparably soft plastic is employed, or it will serve to hold said edge in the preformed groove provided in the base of a spout vformed of a hard plastic.

Example mountings illustrating the invention have been disclosed herein but it is to be understood that variations in the structure and arrangement of the parts may be provided without departing from the spirit and scope of the invention as defined in the appended claims.
